What steps will reproduce the problem?
(1) Open index.html in the browser
(2) Open the console window and its network tab
(4) Click the button several times to show/hide the image container.

What is the expected result?
- The SVG image is only loaded/retrieved once, at page load.

What happens instead?
- The SVG image is reloaded every time the image becomes visible.

Please provide any additional information below. Attach a screenshot if
possible.
- I embed SVG files using <object> in order to enable features such as linked resources.
- There seems to be no reason for this reloading, which delays the display of the image.
- Screenshot attached.
